In this paper, a fault diagnosis algorithm for brushless DC (BLDC) motor drives is proposed to maintain control performance under switch open-damage. The proposed fault diagnosis algorithm consists of a simple algorithm using measured phase current information and it detects open-circuit faults based on the operating characteristic of BLDC motors.

– This paper proposes predictive current control strategy based on predictive direct power control strategy for grid connected three phase voltage source inverter applications. The Proposed strategy uses a symmetrical 4+4 voltage vectors' sequence which selects two effective and two zero voltage vectors and determines concatenated voltage vectors' sequence.(More)
In this paper, interleaved bidirectional DC-DC converter with ZVT cell using a single resonant inductor in continuous conduction mode is proposed. The proposed interleaved bidirectional DC-DC converter has advantages such as a simple circuit, ZVS during wide load range and minimization of current injection effect by using dual current injection time.
